DETAILED DESCRIPTION

Detailed embodiments are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary of various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as illustrations, specimens, models, or patterns. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials, or methods have not been described in detail in order to avoid obscuring the disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art.

Generally described, a carton is formed from a blank. A blank is a sheet of substrate. As used herein, the term “substrate” includes all manner of foldable sheet material such as paperboard, corrugated board, cardboard, plastic, and the like. Exemplary embodiments of cartons described herein are configured to dispense beverage cans. It is envisaged that the cartons can be configured to dispense other articles and/or different arrangements of articles that may be contained within a carton.

Exemplary embodiments of cartons described herein are configured to dispense beverage cans contained therein. However, cartons can be configured to dispense other articles (such as bottles and any other cylindrical items) and/or different arrangements of articles that may be contained within the carton.

As used herein, directional references such as “top”, “bottom”, “base”, “front”, “back”, “rear”, “end”, “side”, “inner”, “outer”, “upper” and “lower” do not necessarily limit the respective panels to such orientation, but may merely serve to distinguish these panels from one another.

As used herein, the term “hingedly connect” refers to all manner of connecting two or more areas or portions of a blank of sheet material, that involves hinge features for facilitating folding the areas or portions of the blank with respect to one another, or otherwise involves structural features that indicate optimal panel folding locations for the blank. Each of such hinge features or structural features may include one or more fold lines.

As used herein, the term “fold line” may refer to one of the following: a scored line, an embossed line, a debossed line, a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cut line, aligned slits, a line of scores and any combination of the aforesaid options. For ease of distinguishing, fold lines are shown as dashed lines in illustrations of blanks.

As used herein, the term “severance line” refers to all manner of lines that facilitate separating portions of the substrate from one another or that indicate optimal separation locations. The term “severance line” may refer to one of the following: a line of perforations, a line of short slits, a line of half-cuts, a single half-cut, an interrupted cut line, aligned slits, and any combination of the aforesaid options.

Those elements of a fold line or a severance line such as cuts, perforations and scores, can be dimensioned and arranged to provide a desired functionality. For example, a line of perforations can be dimensioned or designed with degrees of weakness to define a fold line and/or a severance line. For example, a line of perforations can be designed to facilitate folding and resist breaking in order to provide a fold line, to facilitate folding and facilitate breaking with more effort in order to provide a severance line that can function also as a fold line at least temporarily, or to facilitate breaking with little effort in order to provide a regular severance line.

Referring now to the drawings, wherein like numerals indicate like elements throughout the several views, the drawings illustrate certain of the various aspects of exemplary embodiments of a carton that is configured to dispense articles.

The first wedge panel 162, the second wedge panel 166, and the positioning panel 168 provide rails or beams that support the bottom wall 322 away from the lower edge of the carton 102. The rails are two-ply structures as the first wedge panel 162 overlaps the first side wall 312 (forming a first side rail 362), the second wedge panel 166 overlaps the second side wall 316 (forming a second side rail 364), and the positioning panel 168 overlaps the back wall 318 (forming a back rail 366). The bottom wall 322 is now described in further detail with respect to the formation of the carton 102 from the blank 100.

Referring to FIGS. 1 and 5-7, the carton 102 can be formed from the blank 100 with folding and securing operations described below. For reference, the inside surface of blanks 100 is shown in FIG. 1. The order of the steps can be altered, steps may be added or omitted, and the means for securing components to one another may vary. For example, surfaces of sheet material may be secured together with tape, staples, interlocking folds, hook and loop fasteners, glue, other adhesives, combinations thereof, and the like.

According to a first series of steps, the blank 100 is folded and secured into a collapsed tubular structure. Referring to FIGS. 1 and 5, adhesive is applied to the inside surface of the first wedge panel 162, the inside surface of the second wedge panel 166, and the inside surface of the positioning panel 168. The first bottom panel 152, first wedge panel 162, and gusset panel 182 are folded as a unit along the fold line 170 to overlap the inside surface of the first side panel 112. As such, the inside surface of the first wedge panel 162 is secured to the inside surface of the first side panel 112. The first bottom flap 154 is folded along the fold line 164 such that the inside surface of the first bottom flap 154 is in flat face contact with the inside surface of the front panel 114. The second bottom panel 156, the second wedge panel 166, and the gusset panel 184 are folded as a unit along the fold line 174 to overlap the second side panel 116. As such, the inside surface of the second wedge panel 166 is secured to the inside surface of the second side panel 116. The second bottom flap 158 and the positioning panel 168 are folded as a unit along the fold line 178 to overlap the inside surface of the back panel 118. As such, the inside surface of the positioning panel 168 is secured to the inside surface of the back panel 118.

The gusset panel 182 is folded along the fold line 186 such that the outside surface of the gusset panel 182 is in flat face contact with the outside surface of the first bottom panel 152. The gusset panel 184 is folded along the fold line 188 such that the outside surface of the gusset panel 184 is in flat face contact with the outside surface of the second bottom panel 156. Adhesive is applied to the inside surface of the gusset panel 182 and the gusset panel 184.

Referring to FIGS. 5 and 6, the blank 100 is folded along the fold line 122 such that the inside surface of the gusset panel 182 is in flat face contact with the outside surface of the first bottom flap 154. As such, the gusset panel 182 is secured to the first bottom flap 154. Adhesive is applied to the outside surface of the edge panel 110.

Referring to FIGS. 6 and 7, the blank 100 is folded along the fold line 126 such that the inside surface of the gusset panel 184 is in flat face contact with the outside surface of the second bottom flap 158. As such, the gusset panel 184 is secured to the second bottom flap 158. In addition, the inside surface of the back panel 118 overlaps the outside surface of the edge panel 110. As such, the back panel 118 is secured to the edge panel 110 such that the back panel 118 is hingedly connected to the first side panel 112 along the fold line 120.

Referring to FIG. 7, the blank 100 is formed as a collapsed tubular structure. Referring to FIGS. 3, 4, and 7, the collapsed tubular structure can be erected by folding the blank 100 along the fold line 120, the fold line 122, the fold line 124, and the fold line 126. The collapsed tubular structure is folded until the first side panel 112 is substantially parallel to the second side panel 116 and the front panel 114 is substantially parallel to the back panel 118. Here, the first side panel 112 forms the first side wall 312, the front panel 114 forms the front wall 314, the second side panel 116 forms the second side wall 316, and the back panel 118, forms the back wall 318.

As the first side panel 112 is pulled apart from the front panel 114, the gusset panel 182 folds the first bottom panel 152 down along the fold line 186. When the first side panel 112 is substantially perpendicular to the front panel 114, the first bottom panel 152 is substantially perpendicular to the first side panel 112.

Similarly, as the second side panel 116 is pulled apart from the back panel 118, the gusset panel 184 folds the second bottom panel 156 down along the fold line 188. When the second side panel 116 is substantially perpendicular to the back panel 118, the second bottom panel 156 is substantially perpendicular to the second side panel 116.

As the first bottom panel 152 and the second bottom panel 156 are folded downwardly, they overlap one another and the hooked edge 190 and the hooked edge 192 are adjacent one another. The hooked edge 190 and the hooked edge 192 can engage one another to releasably secure the first bottom panel 152 and the second bottom panel 156 in a folded position. Thereafter the bottom wall 322 is formed as shown in FIGS. 3 and 4.

Cylindrical articles 340 can then be loaded into the carton 102 through the top open end of the carton 102. The cylindrical articles 340 are loaded with their ends adjacent the first side wall 312 and the second side wall 316 and with their side walls configured to roll on the bottom wall 322.

Referring to FIGS. 1 and 2, the top open end of the carton 102 is closed by folding the first top flap 134 and the second top panel 136 inwardly along the fold line 144 and the fold line 148. The second top panel 136 is then folded inwardly along the fold line 146 to overlap the first top flap 134 and the second top panel 136. The tuck flap 260 is folded along the fold line 262 and inserted into the carton 102 with the outside surface of the tuck flap 260 against the inside surface of the first side wall 312. The first top flap 134 is then folded inwardly along the fold line 142 to overlap the second top panel 136. The first elongated opening 242 and the second elongated opening 244 align with the fourth elongated opening 256 and the third elongated opening 254 to form a handle 330. The first securing tab 210 is inserted into the first slot 216 and the second securing tab 212 is inserted into the second slot 214 to releasably secure the first top panel 132 in place and form the top wall 320.

The first side wall 312, the second side wall 316, the top wall 320, and the bottom wall 322 together have a substantially constant cross sectional area along an axis between the front wall 314 and the back wall 318. As such the cylindrical articles 340 can be tightly packed in the carton 102 (e.g., without extra space to move around).

Summarizing the structure of the carton of FIGS. 1-7, the front panel 114 and back panel 118 each is hingedly connected to the first and second side panels 112, 116 to form a collapsible tubular structure that is collapsible into a flat tubular form as shown in FIG. 7. The first bottom panel 152 is connected to the front panel 114 through the first bottom flap 154. The first bottom flap 154 is hingedly connected to the first bottom panel 152 and to the front panel 114 such that the first bottom panel 152 and the first bottom flap 154 are folded into a face contacting arrangement respectively with the first side panel 112 and the front panel 114 when the tubular structure is collapsed into the flat tubular form. The second bottom panel 156 is connected to the back panel 118 through the second bottom flap 158. The second bottom flap 158 is hingedly connected to the second bottom panel 156 and to the back wall 118 such that the second bottom panel 156 and the second bottom flap 158 are folded into a face contacting arrangement respectively with the inside surface of the second side panel 116 and that of the back panel 118 when the tubular structure is collapsed into the flat tubular form.

Referring to FIG. 9, the carton 402 includes as first side wall 614, a top wall 616, a second side wall 618, a bottom wall 622, a front wall 624, and back wall 626. The bottom wall 622 is forward slanted (e.g., at the angle A3 and the angle A4) to move cylindrical articles 640 toward the first side wall 614 where they can be dispensed through an opening created by partially removing the detachable portions 536/546 along the severance lines 530/540.

The bottom wall 622 is recessed. The first wedge panel 412, the second wedge panel 420, and the inside supporting portion 486 space the bottom wall 622 from the lower edge of the carton 402 (e.g., the lower edge of the first side wall 614, second side wall 618, back wall 626). The bottom wall 622 is spaced from the lower edge of the back wall 626 by the height H5 (or height H6 or height H9).

The first wedge panel 412, the second wedge panel 420, and the inside supporting portion 486 provide rails or beams that support the bottom wall 322 away from the lower edge of the carton 102. The rails are two-ply structures as the first wedge panel 412 overlaps the first side wall 614 (forming a first side rail 664), the second wedge panel 420 overlaps the second side wall 618 (forming a second side rail 662), and the inside supporting portion 486 overlaps the back wall 626 (forming a back rail 666).

Referring to FIGS. 8 and 10-11, the carton 402 can be formed from the blank 400 with folding and securing operations described below. For reference, the outside surface of the blank 400 is shown in FIG. 8 and the inside surface of the blank 400 is shown in FIG. 10 (other than folded portions). The order of the steps can be altered, steps may be added or omitted, and the means for securing components to one another may vary. For example, surfaces of sheet material may be secured together with tape, staples, interlocking folds, hook and loop fasteners, glue, other adhesives, combinations thereof, and the like.

According to a first series of steps, the blank 400 is folded and secured into a collapsed tubular structure. Referring to FIG. 8, adhesive is applied to the inside surface of the first connecting panel 410, the inside surface of the first wedge panel 412, and the inside surface of the second wedge panel 420. Referring to FIGS. 8 and 10 the blank 400 is folded along the fold line 432 such that the inside surface of the first connecting panel 410 is secured to the inside surface of the first side panel 414 and inside surface of the first wedge panel 412 is secured to the inside surface of the first side panel 414. The blank 400 is folded along the fold line 438 such that the inside surface of the second wedge panel 420 is secured to the inside surface of the second side panel 418.

Referring to FIGS. 10 and 11, adhesive is applied to the outside surface of the second connecting panel 424 and/or the outside surface of the first connecting panel 410. The blank 400 is folded along the fold line 434 such that the outside surface of the first connecting panel 410 and the outside surface of the second connecting panel 424 are in contact with and secured to one another.

Referring to FIG. 11, the blank 400 is formed as a collapsed tubular structure. The collapsed tubular structure can be erected as a tubular structure with a front open end and a back open end. Referring to FIGS. 11 and 15, the tubular structure is erected by folding the blank 400 along the fold line 430, the fold line 434, the fold line 436, and the fold line 440 to pull the first side panel 414, the top panel 416, the second side panel 418, and the bottom panel 422 away from one another such that panels connected along the fold lines are substantially perpendicular to one another. Referring to FIG. 15, the first side panel 414 forms the first side wall 614, the top panel 416 forms the top wall 616, the second side panel 418 forms the second side wall 618, and the bottom panel 422 is the bottom wall 622.

The front wall 624 is formed at the front open end of the tubular structure. The top front flap 454 is folded inwardly along the fold line 456 and the bottom front flap 462 is folded inwardly along the fold line 464. Adhesive is applied to the outer surface of the top front flap 454 and the outer surface of the bottom front flap 462. The first side front flap 450 is folded inwardly along the fold line 452 to overlap and secure to the top front flap 454 and the bottom front flap 462. Adhesive is applied to the outside surface of the first side front flap 450. The second side front flap 458 is folded inwardly along the fold line 460 to overlap and secure to the top front flap 454, the bottom front flap 462, and the first side front flap 450.

Referring momentarily to FIG. 15, the back open end of the carton 402 is loaded with cylindrical articles 640. Particularly, the carton 402 is placed on the first side wall 614 (or the second side wall 618) so that the cylindrical articles 640 can be loaded onto a flat surface.

Referring to FIGS. 12, 13, and 15, the back wall 626 is formed at the back open end of the tubular structure. The top back flap 474 is folded inwardly along the fold line 476. Adhesive is applied to the outside surface of the top back flap 474 and the inside surface of the inside supporting portion 486. The first side back flap 470 is folded inwardly along the fold line 472 to overlap and secure to the top back flap 474 and the inside supporting portion 486. Adhesive is applied to the outside surface of the first side back flap 470. The second side back flap 478 is folded inwardly along the fold line 480 to overlap and secure to the first side back flap 470, the top back flap 474, and the inside supporting portion 486.

Referring to FIGS. 12-16, adhesive is applied to the inside surface of the outer supporting portion 488. The outer supporting portion 488 is folded along the fold line 490 to overlap and secure to the first side back flap 470 and the second side back flap 478. Thereafter, the carton 402 is formed and can be placed on the rails 662, 664, 666 such that the bottom wall 622 is configured to dispense the cylindrical articles 640.

Referring to FIGS. 17 and 18, another exemplary embodiment is described. The carton 702 is substantially similar to the carton 402, with the exception of a first side back flap 770, a second side back flap 778, and a bottom back flap 782. For clarity, other elements of the carton 702 are not described in detail. Rather, the description provided above with respect to the carton 402 is applicable to the carton 702. Like elements numbers have been used for the carton 702 with the first numeral of the element number increased by three with respect to the element number of the carton 402 for the same element. For example, bottom wall 622 is substantially similar to bottom wall 922.

The first side back flap 770 includes a cutout portion 850 and the second side back flap 778 includes a cutout portion 852. The cutout portion 850 defines a side rail support portion 854 and the cutout portion 852 defines a side rail support portion 856. The cutout portions 850, 852 define portions of the back wall 926 (e.g., side rail support portions 854, 856) that extend below the bottom wall 922 (e.g., the bottom panel 722) adjacent the first wedge panel 712 and the bottom panel 722 to support the side rails 962, 964. In other words, a back rail 966 includes a cutout/

The exemplary side rail support portions 854, 856 are tapered toward the distal edges of the side rails 962, 964. The exemplary side rail support portions 854, 856 provide lateral support to the side rails 962, 964 to keep the side rails 962, 964 from collapsing or folding.

Because of the cutout portions 850, 852, the bottom back flap 782 is a single flap and does not fold over the inside surface and outside surface of the back wall, as does the bottom back flap 482 of the carton 402. The bottom back flap 782 is folded inwardly like the top back flap 774 and the first side back flap 770 and the second side back flap 778 are folded over the outside surface of the top back flap 774 and the bottom back flap 782.
